The inspection machine CVT Slitec was developed by Moeller & Devicon of Bosch Packaging Technology. It splits up the area covered by the camera’s field of view into a number of virtual cameras, which then take several pictures of each individual container, independently of one another. As containers move past these cameras, the system readily identifies any particles allowing the failed containers to be separated out. An important criterion for the quality of an inspection for particles is the False Reject Rate (FRR), which indicates the proportion of good containers wrongly identified by the inspection system as bad. By combining two independent testing stations with the automatic recirculating feature it minimizes the FRR. Special customer-specific checks are also pos-sible. These include cosmetic checks for all types of packaging media for cracks, scratches and chips, as well as packing-specific checks, such as the quality of crimping, cap color on vials or cartridges, neck distortions in ampoules, and defects in the needle shield or plunger stopper in syringes. For the particle inspection, the completely free accessible containers are rotated using individual servomotors for each container. This means that checking of difficult products like suspensions is possible.
